Swap Mechanical HD with insider software to a new hard drive an SSD

Just like to add, unless your external drive is an SSD, don't bother. This game NEEDS an SSD, it will be unplayable on a mechanical hard drive.

I think I know what's this.

It's probably an Xbox one

Try to teardown you Xbox , remove the hard drive, connect it to your computer,

And then connect a 1tb SSD drive

Now you need to copy the hard drive to

The SSD drive , and then wait the computer finished copying all the data to the SSD drive. Now, put the SSD drive inside your Xbox where the hard drive was.

Now try using your Xbox.

Now delete your profile and create a new one because the error code says it's glitched and it's sounds impossible to fix your profile.

Note: the SSD should make your Xbox around 10 times faster loading then the retail one.

Xbox doesnt really support anything less than a 1tb drive . Or recommend it. Try to use officially license xbox hds if possible

Actually the console easily supports drives of 128GB minimum for game storage. But these 'drives' must either be a proper hard drive or an SSD, a Flash drive won't cut it. I've got two drives hooked up, one 2TB HDD and a 500GB SSD. The 500GB SSD is considerably
faster at loading the maps on Battlefield V.

As for the official external drives, there's nothing technically special about them. Inside they're just standard Seagate 2.5" HDD's. Microsoft doesn't even make them. And the SSD Game drives are a complete rip off.

The largest original built in hard drive size is 1TB. While the drive inside the console is a 2.5'' SATA drive, it's not meant to be replaced as others already said.

You would need special software to be able to prepare a new drive for the console as you can't just swap the drives, and the PC is unable to read the Xbox drive without unlicensed software.

Therefore, instructions on how to replace the drive can't be discussed here.

As for the Backup thing: You don't have to. All your savegames are stored in the Xbox Cloud, and only copies of these are stored on the hard drive. Your purchased games are also downloadable again for free.

So if your console breaks, and you get a new one with an empty drive, simply sign in with your Microsoft Account email that you used before, and your games will appear in the "Ready to Install" section of the new console. After starting a game, your save
game will be downloaded as well.

So there is no need to backup anything.

If you're looking to get more storage space, do NOT try to open the console to change the drive. Simply buy yourself a nice USB 3.0 compliant external hard drive (or SSD), and connect that to the console. You can connect up to 3 external drives to your console.

If you have a modern PC with an SSD as a boot drive you shouldn't need to keep resetting/reinstalling Windows. Unlike a mechanical hard drive, Windows won't slow down much on a SSD as long as you keep enough free space.

That being said, the copy protection for Windows Store/Xbox app is far too Draconian.
